provided the operating temperatures and pressures do not exceed the stated 311°F and 711 psig thresholds

Key Benefits Optimized Energy Efficiency: Maximizes use of outdoor air for cooling to lower mechanical energy consumption

such as a boiler or gas manifold

protecting the evaporator coil and fan motor assembly from premature wear caused by debris or bypass air

corrosion-resistant non-metallic cover and straight-through wiring for rapid installation

Markel 43560001 Control 324846-701 provided the operating temperatures andThe Markel 43560001 Control is a heavy duty, factory specified Fan Delay Purge Control designed specifically for the 3480 and RCH Series commercial recessed ceiling heaters. Engineered with an L115 20F thermal switch, this component manages the critical purge cycle by delaying fan deactivation after the heating element cycles off. This thermal management ensures that residual heat is fully dissipated from the element, protecting the internal
